Options

A. First quarter moon
B. Full moon
C. Last quarter moon
D. New moon

Answer

To determine what Rachna will see in the sky next after observing the waning crescent phase of the moon, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Moon Phases**: The moon goes through a series of phases in a cycle, starting from the new moon, moving to the waxing phases (waxing crescent, first quarter, waxing gibbous), reaching the full moon, and then transitioning to the waning phases (waning gibbous, last quarter, waning crescent).

2. **Identify the Current Phase**: Rachna has observed the waning crescent phase. This phase occurs just before the new moon.

3. **Determine the Next Phase**: After the waning crescent phase, the next phase in the lunar cycle is the new moon. During the new moon, the moon is positioned between the Earth and the Sun, and it is not visible from Earth.

4. **Conclusion**: Therefore, after the waning crescent phase, Rachna will see the new moon in the sky next.

### Final Answer:
Rachna will see the **new moon** next.
